This study investigates the high-temperature cyclic oxidation behavior of low-carbon steel coated with Al–FeCr–SiC and Al–FeCr–B 4 C composite coatings prepared by mechanical milling followed by vacuum annealing at 600, 700, and 800 °C for 2 h. Annealing promoted microstructural consolidation and phase evolution, incl…
DRAM capacitor dielectrics face a hard leakage×EOT scaling constraint below the 1z-nm node (IMW 2020); for 30 years industry has responded by doping-pinning the tetragonal phase of high-k dielectrics (ZrO₂/HfO₂-based) to stabilize it—yet this long-standing practice lacks a unified criterion language. Using a field-the…
تحلیل بنیادین، بازنویسی تانسوری و اثبات جامعِ کامل پارادوکس فرمیونهای بدون جرم و چگالی جریان فوقشدید در نانومواد نیمهفلز وایل (The Massless Weyl Fermion Paradox and Ultra-High Current Density in Nanoscale Weyl Semimetals - معمای شماره ۳۰ از ۱۰۰) در بستر فیزیک اطلاعات حمزه (HIP-1155) به شرح زیر است: ۱. مقدمه و معمای…
ABSTRACT The viscoelastic response of crosslinked rubber was investigated using coarse‐grained molecular dynamics simulations combined with time‐temperature superposition. Crosslinked polymer networks containing different numbers of crosslinkers were generated using a dynamic reaction probability model and their mecha…
Organic long persistent luminescence (OLPL) materials are at the forefront of research, undergoing rapid evolution due to their extensive potential applications. The realization of hour-level OLPL, particularly an air-stable one, remains a significant challenge. Here, we developed a new platform to achieve long-term a…
Metal oxide thin film gas sensors have got wide acceptance due to their sensitivity, stability, rapid response-recovery, mechanical and thermal stability, repeatability, reproducibility, crystallinity etc. In the present work pristine and polyaniline (PANI) incorporated SnO 2 thin films were successfully fabricated by…
Gas sensors are extremely important because of their broad application in industrial production and everyday life. However, many conventional gas sensors require high operating temperatures and are fabricated from non-biodegradable materials, leading to increased energy consumption and disposal concerns. To address th…
This paper develops a revised mathematical solution framework for the chemistry challenge "Can autonomous laboratories discover catalysts and operating waveforms together rather than optimizing them separately?". The proposed Mixed-Variable Autonomous Catalyst Search Model (MACSM) was constructed after an earlier form…
Rare-earth-promoted transition metal oxides have attracted significant attention owing to their ability to modify structural, textural, and surface characteristics of functional ceramic materials. In the present work, lanthanum and nickel co-doped oxide systems supported on alumina (Al2O3) and silica (SiO2) were synth…
Abstract Graphene quantum dots (GQDs) and their nitrogen-doped counterparts (N-GQDs) have recently been explored in the management of neurological disorders. However, their biocompatibility remains questionable, particularly subsequent to direct brain exposure. In this study, we investigated the neurotoxicity of GQDs…
FINDING: Five-fold rotational symmetry is forbidden in periodic lattices but emerges in quasicrystals via aperiodic tiling governed by the golden ratio. MATH: Golden ratio φ = (1+√5)/2 ≈ 1.618; its reciprocal φ⁻¹ ≈ 0.618; complex golden ratio ζ = e^(iπ/5) = φ/2 + i√(3-φ)/2 (a 5th root of unity). Penrose tilings use tw…
ABSTRACT To mitigate the trade‐off between flame retardancy and mechanical performance in thermoplastic polyurethane (TPU), an optimized ternary flame‐retardant formulation consisting of hydromagnesite (HM), microencapsulated red phosphorus (MRP), and microencapsulated expandable graphite (MEG) was developed. The ther…
The NiTi alloy has great application potential in the engineering fields involving cavitation. The present study aims to reveal variations in surface and structure characteristics of the NiTi alloy subjected to submerged waterjet. Effects of the standoff distance and cavitation treatment duration were investigated. Th…
The Vyazovkin isoconversional method is widely regarded as a reliable model-free approach for the kinetic analysis of solid-state reactions. However, its direct application is primarily limited to the determination of the activation energy, while the pre-exponential factor and conversion function generally require add…
We present TP-Agent, an autonomous LLM-based agent utilizing a Plan–Execute–Reflect architecture and external computational tools (Python, Mathematica) to assist in theoretical physics research. We evaluate it on two benchmarks: the comprehensive TPBench and the frontier-level PRL-Bench. While TP-Agent demonstrates st…
SIMP steel, a reduced activation ferritic/martensitic heat–resistant steel, is a promising candidate for structural applications in future nuclear fusion reactors. Understanding the evolution of microstructure in SIMP steel is of practical importance for improving the structural integrity of components made from this…
The precise geometric and topological mechanisms governing high-temperature and potential room-temperature superconductivity (RTS) remain obscured by the mathematical rigidity of continuous differential equations. In this paper, we operationalize the theoretical premise that superconductivity is not merely a quantum p…
Supercapacitors offer high power density, fast charging/discharging capability, and long cycle life, yet their relatively low energy density limits broader deployment in electric vehicles, portable electronics, and grid storage systems. MXenes, a family of two-dimensional transition metal carbides, nitrides, and carbo…
Abstract MXenes, a large family of two-dimensional transition-metal carbides and nitrides, have attracted considerable interest owing to their unique physicochemical properties. Structural defects play a key role in tuning these properties, yet their characterization remains highly challenging. Herein, controlled Ne2+…
